DETECTION OF PATHOGENICITY GENES ENCODING ABILITY TO TOXIGENESIS IN ESCHERICHIA COLI ISOLATED FROM THE CHILDREN INTESTINAL BIOTOPE

Shiga toxins (stxs) are the virulence factor of enterohemorrhagic Escherichia coli (EHEC). Shiga toxin-producing Escherichia coli has been recognized as an important food-borne pathogen that causes severe diseases such as a hemolytic uremic syndrome (HUS). Provides information about the species comp...
